For Crohn's Disease, Maintenance I've been on this medicine for 2 months. I feel, most days like I've been in a car accident. The pain is very difficult to handle. I ache like I have the flu. Thinking about not taking good it and take my chances. What could be worse?

For Crohn's Disease, Maintenance I've been using this drug for just over a month and everything seems like it's going down hill. This drug will make me extremely tired but also keep me awake. It's too inconsistent for my body. It should be helping with bodily functions and minimize pain but it does quite the opposite. Some days my body can't move very fast because of the pain. And if it's not the pain it's fatigue all day. I've had the same problem with other drugs like this. There has to be a way to help without all of the drugs or surgeries.

For Bacterial Vaginitis I have taken this medication once before years ago and it was fine. Taking it again now and literally feel like death. It's horrible. I called in sick to work today and most likely will again tomorrow. The first 2 days were fine but after that it's been unbearable. I have diarrhea constantly and it's straight liquid. I puked this morning and been nauseous all day/night, loss of appetite and unbearable stomach pain. I came on this website to see other people's experiences as I was about to go to the emergency cuz this is just ridiculous. Now I know my symptoms are the same as others so I'll just hold off and finish my medication. 3 Days To Go for me and I can't wait to get off of medication. I hope I never have to take this again. Although the the discharge and odor are gone so I know it's doing its work but we just have to suffer through it to get better I guess. Stay strong ladies we can do this.

For Bacterial Vaginitis Hi ladies! So I had BV and went to doctors to get prescription. The doctor prescribed ONE dose of 2000MG ( 4 pills of 500MG) and take it all at once!!! After day two my symptoms are GONE!!! Maybe the doctor should prescribe one dosage for BV as it's very effective!!!!!!!! Consider it
